Title: Transmitter-receiver for smart antenna system of mobile communication base station
Inventor: JEON MIN
IPC: H01Q3/42
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a transmitter-receiver for smart antenna system capable of processing a signal received from N pieces of antenna arrays with a single transmitter-receiver. SOLUTION: Signals received by N pieces of antennas 210 have an fRC center frequency and a BW frequency bandwidth. After a signal passing though a receiving band pass filter 230 is amplified by a low noise amplifier 240, it is mixed with a frequency fi different for every AFEU(antenna front end unit) by a frequency generator 270 to be respectively down-converted to the frequencies of fRC-f1, fRC-f2,..., fRC-fN. Each signal passing though a frequency mixer 290 is respectively filtered by a band pass filter 310. Thus, the received signals of the N pieces of antennas 210 are converted into mutually different signals by passing through N pieces of AFEUs 250 and the N pieces of respective signals pass through an N:1 power combiner 330 to be inputted to a reception inputting means of a wideband transmitter-receiver 340.

Title: Phase synchronizing circuit
Inventor: UCHIDA KATSUMI
IPC: H04L7/033
Filed: 1985-08-09
Abstract: PURPOSE:To improve the stability and accuracy of a phase synchronizing function by providing a pre-signal processing circuit comprising plural edge detection circuits, a delay circuit, a selector control circuit, a selector circuit and a toggle circuit. CONSTITUTION:When an original reception signal phiA2 is inputted to the 1st edge detection circuit 2 of the pre-signal processing circuit 1, edge information EA is detected,fed to a delay circuit 4 and edge information ED is outputted. In this case, when a selector control circuit 5 discriminates the presence of the information EA, a command to receive the information ED is given to a selector circuit 6. When no edge information exists, the circuit 5 gives a command to input the information EB to the circuit 6. The edge information EB, ED obtained in this way are synthesized by the circuit 6 to obtain the edge information ES. The information ES is given to a toggle circuit 7 to obtain a reception signal phiA1 inheriting each phase information of the original reception signal phiA2 and compensating the missing phase information. Thus, the stability and accuracy of the phase synchronizing function are improved.

Filed: 1987-07-14
Abstract: PURPOSE:To eliminate the need to press an operation switch and to improve the operability of the editor of an electrophotographic copying machine by operating the editor interlocked with the detachment of an indication pen from a device main body. CONSTITUTION:When the indication pen 6 is detached for position setting on a tablet 4, an actuator 33 positioned in a hollow part 31 provided to the device main body 30 operates a microswitch 32 and an editor mode is entered through a CPU. Then only coordinate data inputted with the indication pen 6 are made effective. Therefore, when the indication pen of the editor is lifted, the coordinate data to the editor become effective for the 1st time, so wrong input is securely precluded and the operability is improved.
